QUESTIONS AND ANSWERS SURE A+
✔✔Profile Drag - ✔✔Produced mainly by the shape of the aircraft. A smaller slimmer
aircraft reduces profile drag.
✔✔Induced Drag - ✔✔When, at the back of the wing, air flowing rapidly across the top
meets air flowing more slowly underneath, creating a vortex. This type of drag depends
on the performance of the aircraft. When lift, airspeed, and AOA increase, induced drag
automatically increases too.
✔✔When an airplane increases its lift, which statement is true about the air pressure
flowing above and below its wings? - ✔✔Air pressure is lower above the wings and
higher below the wings, producing lift.
✔✔Bernoulli's Principle - ✔✔As the speed of a fluid increases, its pressure decreases.
Air flows faster over the top of the wing leading to lower pressure. Air flows slower on
the bottom of the wing, increasing pressure. Upward push creates lift!
✔✔Longitudinal Axis (Roll) - ✔✔runs lengthwise from the nose to the tail
✔✔Lateral Axis (Pitch) - ✔✔runs wingtip to wingtip
,✔✔Vertical Axis (Yaw) - ✔✔Runs perpendicular to the wings at the center of the aircraft
✔✔Trim - ✔✔Aircraft's desired position.
✔✔Roll - ✔✔along the aircraft's longitudinal axis; controlled by ailerons, located at
trailing edge of the wings.
✔✔Pitch - ✔✔the lateral angle of ascent or descent; controlled by elevators, located in
the rear portion of the horizontal tail assebly
✔✔Yaw - ✔✔Controlled by the rudder, located in the rear part of the tail assembly;
movement of the rudder causes the nose to move from side to side.
✔✔Pressure Altimeter - ✔✔in the cockpit based on atmospheric pressure. Calibrated
automatically for 29.92 of mercury (Hg). Pilot resets the pressure altitudeindicator after
departing an airfieldto ensure the correct pressure altitude of the aircraft is displayed for
the destinatin airfield
✔✔Aircraft perform more efficiently in what weather? - ✔✔Colder wether because the
air is denser than warm air. (Except if air drops too low and de-icing is necessary) [high
air density increases engine performance]
✔✔Fuselage - ✔✔the main body of an aircraft that holds the crew, passengers, and
cargo. Wings, tail, engines, and landing gear attach to the fuselage, so it must be
extremely strong to withstand stresses while minimizing weight. Also helps stabilize
plane in flight
✔✔Truss Struture - ✔✔Consists of welded steel-tubing longerons separated by
diagonal members to endure the loads placed upon the aircraft
✔✔Monocoque Structure - ✔✔consists of a thin sheet-aluminum alloy curved to fit the
shell of the fuselage. This metal skin is designed to withstand the stress of loads and
minimize the total weight the total weight of the aircraft.
✔✔Monocoque Structure - ✔✔consists of a thin sheet-aluminum alloy curved to fit the
shell of the fuselage. This metal skin is designed to withstand the stress of loads and
minimize the total weight the total weight of the aircraft.
✔✔Semi-Cantilever Wing - ✔✔requires both internal bracing and external support from
struts attached to the fuselage
✔✔Biplane - ✔✔an airplane with two pairs of wings
, ✔✔Thickness - ✔✔a percentage of the wing chord; typically ranges from 6.5 to 13.5
percent
✔✔Camber Line - ✔✔amount of curvature of the wing. Imaginary line runs halfway
between upper and lower surfaces of the wing.
✔✔Chord - ✔✔the imaginary line in an airfoil; establishes a baseline for the amount of
camber and width required of the wing along with its wingspan
✔✔How many types of wing platforms are there? - ✔✔4 (rectangular, elliptical, tapered,
and swept)
✔✔Rectangular wing planform - ✔✔the simplest type, highly inefficient, and typically
used for light general aviation
✔✔Elliptical wing planform - ✔✔the most efficient style, with the lowest possible induced
drag
✔✔Tapered wing planform - ✔✔cross between a rectangular and an elliptical, providing
better lift distribution and moderate efficiency. Aircraft with these wings have a wide
range of speeds
✔✔Swept wing planform - ✔✔tapered back to reduce drag. Includes slightly swept,
moderately swept, and sharply swept types. Disadvantages: tendency to twist under
stress
✔✔The amount of lift generated is dependent on the difference between the camber
line and the _________ - ✔✔chord line (when the measurements of the chord line and
camber line differ greatly, the curvature of the wing will provide more lift)
✔✔powerplant - ✔✔encompasses the engines and propellers as well as the induction,
exhaust, electrical, cooling, lubrication, and fuel systems
✔✔reciprocating engine - ✔✔An engine that converts heat energy created by
combusted fuel mixed with air into reciprocating piston movement, which in turn is
converted into a rotary motion via a crankshaft. (typically aircraft with cruising speed not
exceeding 250 mph)
✔✔gas turbine engine - ✔✔Engine that burns natural gas, sending a hot, high-pressure
stream of gas through a turbine connected to an electrical generator. (larger more
powerful planes)
✔✔turbo-supercharged reciprocating engine - ✔✔aircraft traveling at high altitudes
(over 30,000 ft)
